Anyway, the serious point was, at that time I hung out with mechanics, and the usual conversation regarding BLMC cars (and light vans up to Sherpa) was,

"Has it warmed up yet?"

"Dave, do you know where 'engine hot' on this car is?"

<Dave replies>

"Cheers mate; better take it for a run up the bypass then." (this meaning about 2 miles in town and 10 at NSL).

Skoda 078 117 021 A isn't the part's code?

I found mention in Andrt's book, it says special/optional equipment but nothing about origin.. and no mention of thermostat.

 

Trying to find some more info, I only found some old listings, showing that it was made by Autopal (manufacturer of the factory coolant radiators)

And photos of installed cooler

I've searched this but couldn't find a real picture.

It's good to see it finally.

Which is the case without oil cooler as well... Idle, no load:

108ºC at idle!

I think it will pass 140ºC easily when climbing with high rpm.

You owners in hot countries would know better than me but start at 17c cold going to 108c seems high to me, was the engine running at the end of the video or heat soak after engine was turned off?

You have others that know a lot more about this here than I but again it suggests crankcase pressure to me.  Have you tried removing the oil filler cap whilst the engine is running at idle to see if that changes the RPM?   You could also perhaps try running at just about 'MIN' on the engine dipstick and only top up to that level to regularly keep to that level and see if that makes any difference at all, trying the removing oil filler cap at that level too.

 

Different engine I know, but you could also try putting a rubber glove over the oil filler neck with the cap removed and engine running at various RPM, see if it inflates and how much, this was a good display for an A-series engine owner that had had the car and engine for decades and was trying to get to the bottom of why some A-series Spridgets blue -smoked sometimes when other Spridgets never did.

As soon as I find some time, I'll try your suggestions. Thank you.

VW group Oil Cooler

I'm currently using Bosch P3318 oil filter. Which is the same in some VW group engines and it fits to our engine too but thanks to @Papez  now we know, we need a custom made oil filter union bolt to fit these oil coolers.

Do you mean my video?

I was referring to a picture that @Papez had posted.

In my video, it was a very hot day and that's the last part of the 0 to 1600m climb.

 

I have zero idea how hot my oil gets during those trips.

 

@Thefeliciahacker had seen one of these videos before and warned me about that my oil would be boiling.

No, sorry I was referring to Papez's video about the TC6 oil temperature fitting..

 

In my posts with suggestions I see I made a good few typos but I hope you got what I meant.  For engine breathing do double check you've put everything back as it should be and that there are no blockages and check any vacuums (do you have servo brakes).

Sounds like the engine wasn't running at the end of the video.. but the "heating up at idle" part went up to 106C.

Before the radiator fan turns on, the coolant can reach around 100-105°. Since the oil at this phase cools only by contact with the engine block (no airflow around the oil sump), these temps are IMO not impossible.

I tried to find some data about oil temps on stock engines, and found a topic where people reported temps of newer Skodas with 1.0 N/A engines (no oil cooler) - they go up to around 130° on highways, 110 is standard temp at lower cruising speeds. TSIs with heat exchangers usually top around 110C. Someone mentioned old 1.2 three-cylinders, they supposedly went up to 150C, although that's unverified, oil overheating due to heat from the catalytic converter is a documented issue on those engines.

If someone wants to install an oil temp gauge sensor, which of the three plugs shown above would be the most suitable for an accurate reading of the oil temp?

I had one in the past, a custom hexagon tube fitted and the gauge had his own sensor.

Was teplacing the factory switch although some mechanics (back then) disagree because with the new aftermarket gauge yes you had precise indications but no red warning light in the dashboard (as you could have with the factory).

Now things have changed, an example:

That would be my point, the car is static and not going along the road, though of course heavy load on the engine would warm things.  I did notice the the needle of the water gauge rise and was lower at end so assumed the electric fan(s) had cut in,  I'd hope that R_Blue's oil didn't get to 140C given his water temp readings but I don't know the car, engine, weather and climbs.

 

I also wondered about the pickup position and placement, how well the thermistor is embedded and insulated in the sandwich plate as the exhaust looked fairly close to it and filter but perhaps it isn't and there's cooling air that gets there.

 

My wife's 2015 1.2 TSI usually shows  [ETA; oil temperature* of ] 96c, summer or winter, I have had it in treble digits when I gave the car a couple of blow-out runs for a few miles on reasonably mild day and cold night weather (above freezing though) this was with no passengers or luggage or rubbish (well nothing that weighed anything) in the car, flat road, constant speed.

 

* ETA: biased gauge needle for coolant remains at rocky steady 90c as far as I've noticed

In my experience of looking up and cross referencing oil filters amalgamation of databases for various car models and applying supersedes the end databases have errors so because as what they sometimes say will, or perhaps will not, fit or be suitable, or perhaps be unsuitable, can be wrong.  Also they sometimes list a part that will only fit specific models in a range without making that clear or at all.

I have never seen that number for about 20 years that i have gauge (old and newer) in my console, except in case of a problem.

Full heated (for example in city traffic for about two hours) in summer it barely shows 90 'C, while traveling is at least 2-4 'C less.

I forgot to put your car seemed to go very well up that climb at those speeds and temperatures, if you were only showing 84c, or around that, coolant temperature then perhaps you might be better served at the moment (and future) with an oil pressure gauge than oil temperature gauge, at least for now if only a temporary installation.

This depends on fan's thermoswitch - stock on a non-ac Felicia is TH470.2, which set quite high, at 97C +2/-3.. Add delay before the hot coolant gets from thermostat to rad output, older switch that can drift from rated temp and you can get close to 110° quite easily.

My point was, that temperatures beyond coolant temp aren't rare, so even exchanger can have a positive effect. Which is probably why VW slaps it on almost every engine, except those that needed it the most 😁

It's not been confirmed that there is an issue with oil pressure but an oil pressure  gauge might well help to confirm or refute plus the gauge will show pressure at different points and circumstances so that if there is an issue it can be seen when this starts, continues and stops and in relation to other gauges' readings and the driving circumstances to the engine at those times.

 

An oil temperature gauge is useful to confirm when the oil has fully warmed up or possibly if it's getting too warm/hot but the coolant gauge seems to be doing a reasonable/good job already, an engine can run with cold or hot oil but not so well without pressure.  An oil pressure gauge will probably show dramatic oil loss (say from an oil pipe off or cut or whatever) more instantly that the oil temperature gauge.

 

The standard old British sportscars had oil pressure gauges rather than oil temperature gauges, when I had one with an oil temperature it just gave me more to worry about when driving the car in winter and driving circumstances precluded the car in a way to warm the oil quicker.

 

If you put a pressure gauge in your car it would perhaps give you a little more info into the various engine oils - but also more to worry about.

Yeap I take your point but for those that want to much better oils are available today over a wider selection.

 

I don't think  R_Blue's car would ever need an oil cooler if it was in the UK.  I might be tempted to say for such cars and their VW engines VW might need to put on oil coolers to cover car and engine mistakes and compromises but of course I'd never suggest such.  Did I ever mention Škoda quality went down when VW first took them over. 😁

 

ETA: I find I can remember the keyboard shortcut for Š, must have sunk into my shrivelled brain subliminally .

My worst temperature scores were with stock thermoswitch (87-92) and that damned coolant sensors with the yellow ring.

Above 130deg is race oil territory 

As the 1.2 TSI has been mentioned the following is from the Owner's Manual (front title cover in error shows "Operating Instructions") for my wife's 2015 Fabia Mk3, it normally shows about 93=96c when we've checked and on a couple of blow-out runs I done I've seen IIRC about 102-4c but I was going at a lot higher speed that usual.
